Aiper backs it with a 2-year warranty. Our score weighs specs, features and buyer feedback against what you're shopping for.
Who should buy the Aiper Scuba S1?
Buy it if your pool collects both fine dust and leaves and you want the waterline handled too. The dual filtration and four-zone coverage target exactly those jobs.
It also fits if you like setting a weekly schedule and letting the robot work on its own.
The app adds real flexibility. Eco Mode stretches runtime to 270 minutes for light daily cleaning.
Auto, Floor, Wall and Scheduled modes run up to 180 minutes when you want a deeper pass. A weekly custom cleaning plan means you set it once and stop thinking about it.
Skip it if your pool has no walls or waterline worth climbing. You would pay for features you never use, and a floor-only robot would do the same job.
If your pool is above-ground and compact, the Dolphin Nautilus AG is the simpler match. If you are still weighing robot cleaning against manual vacuuming, read are robotic pool cleaners worth it before you decide.
The specs that matter in daily use
Runtime and navigation are the two specs you will feel every day. Aiper lists up to 270 minutes in Eco Mode and up to 180 minutes in the active modes.
That split matters: light maintenance can run long, while a full floor-and-wall pass uses more battery.
The navigation setup is the other daily factor. Aiper says the Scuba S1 uses 11 high-precision sensors and dual-path algorithms.
The WavePath pattern is meant to cover the pool with little overlap. Adaptive navigation reads the pool layout as it moves, so it should not leave obvious missed patches.
Cleaning ability comes down to the filters and the treads. The 3-micron filter catches dust and sand; the 180-micron filter holds leaves and larger debris.
Aiper uses a Caterpillar Treads system to help the robot climb walls and hold on in the shallow areas above 12 inches.
One practical limit is battery power. A cordless robot needs a recharge between longer runs.
A corded model stays plugged in but ties you to an outlet and a cord in the water. Weigh that against how often you plan to run it.
For the full routine, our guide on how to vacuum a pool with a robotic cleaner walks through the steps.
Setting up the Aiper Scuba S1
Setup starts with the app. Aiper lists App Support as a main feature, so plan on pairing the robot to your phone before the first run.
The app is also where you pick Eco, Auto, Floor, Wall or Scheduled mode and set the weekly plan.
Charge the battery before the first cleaning. Aiper lists one nonstandard battery and a battery-powered source, so the robot runs free of cords in the pool.
Check the charge level in the app before you lower it in.
Place the robot in the pool and let it settle. The sensors and adaptive navigation do the route planning.
On the first run, watch how it handles your steps, corners and shallow shelf, since those are the spots most likely to need a second pass.
Set the weekly schedule once you know the coverage works. A scheduled plan is the feature that makes a robot feel hands-off.
Aiper lists Scheduled mode with a Weekly Custom Cleaning Plan, so you can match runs to your pool's debris pattern. Pick Eco Mode for light days and the active modes when the pool needs more.
If the robot misses a spot in the shallow area, check that the water depth there is above 12 inches as Aiper states. Shallow shelves below that may not get the full treatment.
Run a floor-only pass to see whether the miss is about depth or about debris type.
Filter care and keeping the robot clean
Filter care is the maintenance task you cannot skip. The dual-layer system only works when both filters are clear.
A clogged 3-micron layer stops catching dust and makes the robot work harder.
Pull the filter assembly after each run and rinse it. Aiper lists a replaceable 3-micron ultra-fine filter and a 180-micron standard filter.
The coarse layer holds leaves; the fine layer traps sand and dust. Rinse the coarse filter first, then the fine one, so you can see what each caught.
Replace the 3-micron filter when rinsing no longer clears it. Fine filters wear out faster than coarse ones because they catch the smallest particles.
Budget for replacements as part of ownership, the same way you would for any pool filter media.
Wipe the treads and the waterline contact points. Grit stuck in the treads weakens climbing grip.
A quick rinse after each run keeps the Caterpillar Treads working as Aiper designed them.
Check the battery contacts and the charging setup between runs. A cordless robot lives or dies by its charge.
Store it out of direct sun when it is not in the pool. If your pool also fights algae, our post on whether robotic pool cleaners pick up algae explains what a robot can and cannot do.
The trade-offs to know before you buy
The biggest trade-off is battery power. The Scuba S1 runs on one nonstandard battery.
That means a charge cycle between longer runs and a battery that will eventually need replacing. A corded robot avoids both, but it ties you to an outlet and leaves a cord in the water.
The second trade-off is mode management. The app gives you Eco, Auto, Floor, Wall and Scheduled modes, which is great for control but asks you to think about which mode fits the day.
If you want one button and no app, this robot offers more control than you need.
Wall climbing is also a battery cost. Climbing walls and scrubbing the waterline use more energy than a floor-only pass.
The 270-minute Eco Mode figure applies to light maintenance, not a full four-zone run. The active modes run up to 180 minutes, and that is the number to plan around for deep cleaning.
None of these are deal-breakers for the right pool. They are the reasons this robot suits owners who want coverage and control, and not owners who want the simplest possible machine.
How the Aiper Scuba S1 compares with the alternatives
Two other robots make sense depending on your pool. The Dolphin Nautilus AG is built for above-ground pools and cleans floors only.
The 2026 Release Robotic Pool Vacuum (Wall Climbing) offers longer runtime for larger pools. Here is how each one fits.
Dolphin Nautilus AG: best for above-ground pool floors
The Dolphin Nautilus AG scores 8.6 and is the top pick here for above-ground pool floors. Its active scrubbing brush goes after debris on the floor, and the top-load filter basket is easy to lift and empty.
Dolphin says it cleans a pool in 1.5 hours and is built for above-ground pools up to 33 ft in length.
The catch is coverage. Dolphin states plainly that the Nautilus AG does not clean walls or the waterline.
If your pool builds a scum line or algae on the walls, you still scrub those by hand. It also runs on AC/DC power, so it needs an outlet near the pool.
Pick it when your pool is above-ground, compact and mostly floor to clean. Pick the Aiper when the waterline matters too.
If budget is the deciding factor, our roundup of robotic pool cleaners under 500 compares the value options.
2026 Release Robotic Pool Vacuum (Wall Climbing): best for long runtime and large pools
The 2026 Release Robotic Pool Vacuum (Wall Climbing) scores 7.6 and suits larger pools that need a long run. Its maker lists up to 190 minutes of runtime, coverage up to 2150 sq ft and a recharge in about 3 hours.
It climbs slopes up to 40 degrees and uses 2.0 sonar navigation. Dual brushless motors run at 3200 RPM with 4800 GPH of suction.
The Aiper wins on flexibility. It has Eco Mode for long light runs and a weekly schedule in the app.
The 2026 Release model's edge is raw runtime and area coverage for a big pool in one pass. Its 40-degree climbing limit means steep or odd wall shapes can stop it.
Pick the 2026 Release model for size and runtime; pick the Aiper for waterline cleaning and app control. Neither is the floor-only simplicity of the Dolphin.
Verdict: should you buy the Aiper Scuba S1?
Buy the Aiper Scuba S1 if you want four-zone cleaning from one cordless robot. The dual filtration handles both fine dust and leaves, the app adds a weekly schedule, and Aiper backs it with a 2-year warranty.
For a pool with walls and a waterline that need regular attention, it does the most work per run.
Skip it if your pool is above-ground and floor-focused. The Dolphin Nautilus AG cleans that job in 1.5 hours with active scrubbing and a simpler filter basket.
Choose the 2026 Release Robotic Pool Vacuum (Wall Climbing) if you have a large pool and runtime matters more than app control. The Aiper sits in the middle: more coverage than the Dolphin, more control than the 2026 Release model.
The deciding question is simple. Does your pool have a waterline and walls you want handled automatically?
If yes, this Aiper Scuba S1 review points you to a buy. If your cleaning is all floor, save the coverage features for a pool that needs them and go with the Dolphin.

Frequently asked questions
Is the Aiper Scuba S1 worth buying?
It is worth buying if you want floor, wall and waterline cleaning from one cordless robot. The dual filtration and weekly schedule suit pools that collect both fine dust and leaves.
Choose a corded floor-only robot if your pool has no walls to climb and you want the simplest possible setup.
How long does the Aiper Scuba S1 run on one charge?
Aiper says Eco Mode gives up to 270 minutes, while Auto, Floor, Wall and Scheduled modes run up to 180 minutes. Longer runs suit daily light cleaning.
Pick shorter modes when you want a deeper pass, and plan a recharge between runs.
Does the Aiper Scuba S1 clean the waterline?
Yes. Aiper lists waterline cleaning along with the floor, walls and shallow areas above 12 inches.
That makes it a fit for pools that build a scum line at the water's edge.
A floor-only robot leaves that band for you to scrub by hand.
What filters does the Aiper Scuba S1 use?
It has dual filtration: a replaceable 3-micron ultra-fine filter paired with a 180-micron standard filter. The finer layer traps dust and sand that a single coarse basket lets through.
Aiper lists both filters as part of the cleaning system, so budget for replacements over time.
Does the Aiper Scuba S1 come with a warranty?
Aiper backs the Scuba S1 with a 2-year warranty. Keep your receipt and model number in case you need service.
